Crow, 9451 ElGranito, La Mesa, Calif. 92041 Filed Sept. 8, 1965, Ser. No. 485,698 3Claims. (Cl. 128-294) The present invention relates to an internalprophylactic appliance, and more particularly, to an internalprophylactic appliance for insertion in the urethrae.

According to the invention, an open ended tubular member constructed ofa porous flexible material, such as styrene, rubber or plastic, isprovided for insertion therein of an absorption member conforming to theinner dimensions of the open ended tubular member. The absorption memberis also preferably constructed of foam of the styrene rubber or plastictypes for maximum absorption and flexibility. For maximum protection, aspermicidal jelly is carried within the pores of the open ended tubularmember for forming a seal when combined with sperm at the time ofejaculation. Both the open ended tubular member and the absorptionmember can be enclosed by a gelatin capsule designed to dissolve at bodytemperature. The entire assembly can then be easily forced through theexternal urethral orifice into the fossa navicularis urethrae, at whichtime the gelation capsule will dissolve, allowing the open ended tubularmember and its inserted absorption member to expand to its uncompressedstate within the fossa navicularis urethrae. Due to the anatomy of thisportion of the urethrae, the entire prophylactic will be held in place,and can be easily removed at the convenience of the wearer.

An object of the present invention is the provision of an internalprophylactic appliance which can easily and conveniently be inserted andremoved.

Another object of the invention is the provision of an internalprophylactic appliance which can be utilized with a minimum ofdiscomfort to the wearer.

A further object of the present invention is the provision of aninternal prophylactic appliance which is simple and inexpensive tomanufacture.

Other objects and many of the attendant advantages of this inventionwill be readily appreciated as the same becomes better understood byreference to the following detailed description, when considered inconnection with the accompanying drawing, in which like referencednumerals designate like parts throughout the figures thereof, andwherein:

FIG. 1 is a schematic representation of the urethrae;

FIG. 2 is an exploded cross-sectional view of the preferred embodimentof the present invention; and

FIG. 3 is a schematic diagram of the urethrae with the internalprophylactic appliance of the present invention in place.

Referring to FIG. 1, a section of a penis is shown generally at 11having the body portion generally at 12 and the glans portion at 13. Thecorpus cavernosum urethrae is shown at 14, widening at 16 at the fossanavicularis urethrae, and contracting again at 17, just prior to theorificium urethrae externum 18.

Referring to FIG. 2, external porous member 21 has recess 22 forcooperation with internal absorption member 23. Gelatin capsule halves24 and 26 compress outer porous member 21 and inner absorption member 223, and completely encapsulates members 21 and 23 when assembled.

Referring to FIG. 3, outer porous member 21 and inner absorption member23 are shown placed within the fossa navicularis urethrae 16 having anappendage 27 protruding from the orificium urethrae externum 18, andbeing compressed at the fossa navicularis urethrae 17.

The internal prophylactic appliance of the present in vention is basedupon the anatomy of the urethrae portion of the penis. It is well knownthat the dilated portion of the urethrae, i.e., the fossa navicularisurethrae, is the most susceptible portion to expansion. Hence, if aporous or foam material is compressed and placed within this portion ofthe urethrae, it will expand to its uncompressed state causing a minimumof discomfort to the wearer. This is accomplished by the appliance whichhas been described above, in that the outer absorption member or porousmember 21 is compressed within gelatin halves 24 and 26. Porous member21 is impregnated with a spermicidal compound such asmethoxypolyoxyethyleneglycol or nonylphenorpolyethoxyethanol. This willeffect a congealing upon contact with sperm at the time of ejaculation,sealing the outer member 21 and allowing for the containment of thesemen Within absorption member 23, since both outer members 21 and 23can expand within the fossa navicularis urethrae 16. At the time ofinsertion, gelatin capsule halves 24 and 26 dissolve, allowing for aninitial expansion of members 21 and 23, as shown in FIG. 3, i.e., theywill expand to their uncompressed state as shown in FIG. 2. Appendage 27is created by constriction 17 separating the fossa navicularis urethrae16 and the orificium urethrae eX- ternum 18. Extension 27 effects easyremoval after use.

At the time of ejaculation, semen enters inner absorption member 23 andoutward into outer foam member 21. At the time the semen enters outermember 21, the spermicidal jelly causes it to congeal, forming a sealwhich will not allow passage therethrough. Both foam members 21 and 23will then expand further in the fossa navicularis urethrae, as necessaryfor total absorption of the semen.

It should be understood, of course, that the foregoing disclosurerelates to only a preferred embodiment of the invention, and that it isintended to cover all changes and modifications of the examples of theinvention herein chosen for the purposes of the disclosure, which do notconstitute departures from the spirit and scope of the invention.
